... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...

... Tidal circularisation of white dwarfs and formation of sources of gravitational waves in globular clusters . ... I point out that a major fraction of white dwarfs tidally captured by the black hole may be destroyed by tidal inflation and rotational break-up during ongoing tidal circularisation, and therefore the formation of tight binaries is inhibited. However, some fraction may survive tidal circularisation through being spun up to high rotation rates where tidal interactions are less effetive. ...
